LITTLE ROCK  Interstate 30 has reopened between Arkadelphia and Malvern after being closed more than 12 hours after a crash spilled hazardous materials on the roadway.

Arkansas State Police said at 8:30 a.m. that the highway had just reopened to westbound traffic. The eastbound lanes had been cleared a short time earlier.

Both directions were closed all night and into the morning between the 78 and 98 mile markers. Traffic was rerouted onto Highway 67.

Police said an 18-wheeler carrying propyl acetate, a flammable liquid, wrecked around 7:15 p.m. Wednesday near the 86 mile marker, spilling at least some of its load. It wasn't clear if there were injuries.
